Re: Containers, virtual machines resemble each other, except they're different
Yes, in theory, more complexity, but containers resolve many complex issues related to portability and deployment, and I think it's inevitable that IT will make use of them. I don't think it will be that hard to figure where they're best used. Virtual desktop infrastructure, where large groups of users get assigned the same desktop, and they need to be spun up quickly, might turn out to be one.

Re: Containers, virtual machines resemble each other, except they're different
Charlie, Asking IT to choose between containers vs. VMs for various workloads is adding more complexity -- not to say that's not worthwhile for the benefits. But it's one more decision to be made.

Containers, virtual machines resemble each other, except they're different
The management capabiltiies for containers are likely to be developed quickly and proceed down different paths than virtualization has -- thnik DevOps with more stuff running on bare metal. Both will have immense benefits and both will be part of a future, software-defined data center. Containers and virtual machines resemble each other in their ability to move jobs around and the isolation they impose on the workload. Otherwise, they're different.

He makes good points
If you're running an application in a hybrid model, it's likely because it's important and has some complicated dependencies. And, Docker and containers are still in early days for most companies.

important point
"But the enterprise has a lot of diverse applications. Some will run well in containers and sometimes those containers will be run inside a virtual machine in the cloud for the management advantages the virtualization adds to the picture." This is really important in light of the Docker discussions this week. The fit will vary depending on app. This is not an either/or decision: Enterprises will mix.
